Description

An automatic spot welding device for a diaphragm

technical field

The utility model relates to an automatic spot welding device, in particular to an automatic spot welding device for a diaphragm.

Background technique

In modern industry, a large number of welding processes have been used to manufacture metal and non-metal structures. In the entire industrial system, it is difficult to find industries that do not use welding structures. Among various welding methods, spot welding is often used for thin plate welding. .

Spot welding is a high-speed and economical connection method. It is suitable for the manufacture of stamped and rolled sheet members that can be overlapped, the joints do not require airtightness, and the thickness is less than 3mm. It is to weld the weldment on the contact surface of the joint. Individual spot welding, spot welding requires the metal to have better plasticity. When welding, first clean the surface of the weldment, and then assemble the welded sheet metal lap joint, press it between the two columnar copper electrodes, and apply pressure to compress it. When a sufficiently large current is passed, a large amount of resistance heat is generated at the contact of the plates, and the metal in the hottest area in the center is quickly heated to a highly plastic or molten state, forming a lens-shaped liquid molten pool. The pressure is maintained, the current is disconnected, and as the metal cools, a solder joint is formed.

The traditional spot welding operation needs to manually place the material into the feeding trough of the spot welding machine, and then the operator touches the start button, and the spot welding machine starts the spot welding work. After the workpiece is welded, the operator takes out the material , and then put another sheet into the feeding trough, and press the start button to start the welding operation of the next cycle. In this production process, a fixed operator is needed, and the work efficiency of the operator will directly determine the output of spot welding production.

For example, the welding of batteries and soldering tabs is mainly by manual welding. During the welding process of batteries and soldering tabs, the batteries and soldering tabs need to be manually fed, and the production efficiency is low. Such as the welding of the mass sheet and the diaphragm of the buzzer, the existing technology usually uses manual tweezers to put the mass sheet and the diaphragm into the positioning grooves of the mass sheet and the diaphragm, and then step on the foot switch with the foot to Complete the spot welding of the mass sheet and the diaphragm, and finally manually put the finished product into the receiving box with tweezers. They all have the problems and deficiencies of high labor cost, low efficiency, and high work intensity.

After spot welding delay time arrives, upper electrode 52 begins to rise, and lower electrode 56 begins to descend, and after upper electrode rises in place, and lower electrode falls in place, send the signal of spot welding to control mechanism 7.

4. The action of the blanking mechanism:

After the first diaphragm and the second diaphragm in the positioning sleeve are welded, they continue to rotate with the indexing turntable for a predetermined angle, 60° to move the positioning sleeve to the unloading mechanism.

Then, the third translation cylinder 60 in the blanking mechanism drives the third horizontal piston rod 58 to stretch out. After the movement is in place, the third lift cylinder 61 starts to drive the third vertical piston rod 62 to perform a downward movement. After falling in place, The third vacuum suction nozzle 57 starts to suck material. After the material suction time is up, the third lifting cylinder 61 drives the third vertical piston rod 62 to move up. Retraction movement, after retracting back to the place, the 3rd vacuum suction nozzle 57 starts to discharge product, after release time arrives, sends blanking completion signal to control mechanism 7.

After the blanking is completed, enter the next cycle and repeat the above 1 to 4 actions to realize automatic production.
